【Abstract】 Backgrounded with the strengthening construction of the main bridge of Burri Bridge,Khartoum State,Sudan,the vibration behavior of T-frame bridges strengthened with external prestressing is studied by means of universal finite element software ANSYS,and measures against resonance of the T-frame bridge structures are proposed.The analysis and measures in the paper are of practical values in guiding construction of bridge works.更多还原
